Parapodium.| ASCLEPIADEX (Brown). 559 
name (Drége, 3421) with that specimen, because E. Meyer’s manuscript descrip- 
tion of Parapodium placed with it, describes a totally different floral stracture, 
and his dissected flower, which is also on the same sheet, agrees with his 
description and with the flowers of the plant I have above described as P. 
costatum. Specimens of it, collected by Drége, have been erroneously distributed 
as Pachycarpus rigidus, E. Meyer, so that great confusion seems to have been 
made in the distribution of these three species. 
2. P. simile (N. E. Br.) ; stems apparently about 6-10 in. high, 
2-3 lin. thick, bifariously puberulous, leafy to the base; leaves 
spreading or ascending; petiole 1—8 in. long, channelled and puberu- 
lous above ; blade 11-31 in. long, 23-10 lin. broad, oblong, lanceo- 
late-oblong or oblong-linear, acute, rounded or cuneate at the. base, 
coriaceous, flat, not crisped at the margins, glabrous on both sides; 
umbels 4-6, lateral at the nodes, peduneulate, 8—9-flowered ; 
peduncles 1-1 in. long, moderately stout, puberulous on one side ; 
bracts 2-3 lin. long, linear-subulate, finely pointed, glabrous, 
minutely and sparsely ciliate; pedicels 4-1 in. long, puberulous on 
one side; sepals 1 in. long, 3-1 lin. broad, lanceolate, acuminate, 
with a few hairs on the back or subglabrous, applied to the corolla, 
with spreading tips ; corolla subglobose-campanulate, quite glabrous, 
‘‘creamy-brown’’ according to Miss Pegler, dark purple-brown 
with pale margins to the lobes in the dried state; tube 1-1} in. 
long; lobes about 3 lin. long, erect and contiguous at the very 
concave lower part, recurved at the flat tips, revolute along the 
margins; corona-lobes arising just below the sinuses between the 
corolla-lobes and decurrent-adnate to the bottom of the corolla, 
¢ lin. high, 12 lin. broad, transversely oblong, subtruncately rounded 
at the top, which has an acute edge, fleshy, white, erect, contiguous 
at their sides, which are slightly reflexed, forming a pentagonal cup 
surrounding, but free from, the 2 lin. long staminal column ; anther- 
appendages ovate, with the margins recurved as if pinched just 
below the truncate apex, erect, applied to the sides of the style- 
apex ; anther-wings triangular in outline, acute at the apex and not 
1 as broad just below as atthe acutely hooked-angular base, nearly 
straight on their outer margin; style-apex shortly columnar or 
subconical, minutely bilobed, not exserted beyond the anther-appen- 
dages ; follicle solitary, erect, very large in proportion to the plant, 
5 in. or more long, 1 in. thick, lanceolate, truncate and somewhat 
toothed at the apex, with about 5 coriaceous irregularly toothed 
wings, teeth 1-1 in. long; seeds (unripe) ovate, very concave on one 
side, convex on the other, rugose, dark brown, probably about 2 lin. 
long when ripe.

Although similar to P. costatum, the short style-apex and rather smaller 
differently shaped anther-wings clearly point to a specific distinction. The 
follicles of P. costatum may also prove to be different from those of this plant.
